STEAM-TRAP.

SPECFICATIGN forming part of Letters Patent No. 683,598, dated October 1, 1901.

Application iiletl April 4, 1901.

To all whom, t may concern:

Be it known that we, AUGUST SILK and PETER LIGHT, citizens of the United States, and residents of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Steam-Traps; and We do hereby declare the following to be a clear,

full,and exact description thereof, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form also a part of this specification.

This invention relates to certain improvements in details of construction, as more fully set forth hereinafter.

In the following specification and particularly pointed out in the claim at the end thereof is found a full description of the invention, together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which- Figure lis a side view of our trap complete. Fig. 2 is a longitudinal section of the same. Fig. 3 is a top view with the inlet-opening open and parts broken away. Fig. 4 is a vertical cross-section on lines 4 4 of Fig. 2. Fig. 5 is a similar section on lines 5 5 of Fig. 2.

9 is a housing of suitable shape and size, which may be supported in any convenient manner-as, for instance, it may rest on legs 10. It has an access-opening 11 to permit access for placing the operating parts and for any other purposes, which opening is normally closed by a cap 12. In its upper part it is provided with a steam-inlet 13 and in its lower part with an outlet 14 to permit exit of the accumulatingcondensation. This outlet is controlled by a valve 15, supported so as to be capable of moving in a vertical direction This valve-seat forms part of a nipple 17, which serves at the same time as a means for connecting the outlet-pipe 18. This nipple is held in position by means of a union-coupling 19 to a plug 2l, which screws in the outlet-opening 14 of the housing. For its movement valve 15 is connected to rod y22, heldin upright position by a guide 23. The upper end of this rod is loosely hung onto the free end of an angle-lever 24, the other end of which enlarges into a hub and Serial No. 54,237. (No model.)

by means of lateral trunnion-bearings 25 is pivotally supported between the forked branches 26 of a bracket 27. The other end of this bracket is attached to the inside of the housing, preferably to'a projecting flange 28 therein. Through the pivot-ed end or hub of the angle-lever and held therein passes an arm 29, which on its free end carries a float 31. It will now be understood that as soon as the accumulated condensation lifts the float the outlet-valve follows and permits exit of part of the accumulation until this latter recedes to its normal level, when said valve closes again. The oscillations of this ioat and the time with reference to the accumulating condensation when the same lifts the valve may be accurately regulated by means of an adjustable weight 32, mounted near the' other end of arm 29. The action of the valve is very prompt and quite sensitive to the actions of the fioat, to the movements of which it responds freely, since the center on which its supporting-arm swings is coincident with the fulcrum of the angle-lever. The inletopening is provided with a pipe 33, the discharge end of which is carried close to the bottom of the housing, so as to be below the condensed water therein. This insures a quick condensation of any entering steam and also prevents disturbance of the position of the parts within or of the surface of the Water, so that the only motion within is such as is due to the movement of the float.

Steam-traps accumulate usually more or less sediment, which requires removal from time to time. We use the normal outletvalve to do this and accordingly provide means whereby this valve may be raised and held open independent of the float.A For such purpose we provide a rod 34, disposed transversely below the float-arm 29 and supported in the sides of the housing. It is provided with a projection in the shape of an eccentrically-mounted cam 35, which is so attached as to be below float-arm 29, so that when rod 34 is rotated it is capable of raising said arm. For its manipulation one end at least of this rod projects to the outside of the housing, where it is provided with a handle 36. Normally it is so turned that this projection 35 does not come in contact with arm 29 when the float is in its lowest position, so as not to interfere Y this rod passes through the sides of the housing it is necessary to provide stuffing-boxes 3S. In view of the fact that we use this outlet-valve also as a blow-off valve we favor the accumulation of sediment near it and its movement toward it by providing` a pocket 39, in the deepest part of which the outlet is located.

41 is a conventional glass gage to show the level of accumulation.

It will be noted that the moving parts of this valve are reduced to a minimum, thus reducing friction and. Wear, all of which results in a device reliable and effective in operation and quickly affected by any variations in the level of the accumulations. While all parts are inclosed, they are also readily accessible for inspection and repair or renewal, and parts most subject to wear, like valve 15, may be had access to and renewed from the outside by simply removing coupling 19.

Having described our invention, we claim as new- In a steam-trap, the combination of a boxshaped housing, an access-opening in its top, a cap to close this opening, a steam-inlet, a pocket 39 formed by a depression in its otherwise fiat bottom, an outlet-opening in the deepest part of this pocket, a combined pipeattaching nipple 17, and valve-seat 16, a plug 21 fitted into the outlet-opening, a coupling whereby this nipple is detachably connected in position below the outlet-opening, avalve 15 fitted to valve-seat 16, a rod 22, to the lower end of which valve 15 is connected, an angle-lever 24, to the free end of which the upper end of this rod is att-ached and the other end of which is laterally enlarged to form a hub with trunuions 25 on both sides, a bracket 27 having downwardly-projecting branches 26 between which these trunnions are pivotally supported, an interior flange 28 to which this bracket is attached, the point of attachment being immediately below the access-opening in the top of the trap, an arm 29 passing centrally through the hub of the angle-lever, a iioat at the free end of this arm to automatically actuate the angle-lever and means accessible from the outside to positively raise this arm.

In testimony whereof we hereunto set our hands in the presence of two witnesses.
